Description
Is a vector pointing up that specifies the orientation of this 3D object.
Read the AbsoluteUp property to obtain a vector pointing up that specifies the orientation of this 3D object. AbsoluteUp is of type tagVECTOR3D and has its X
, Y
, Z
, and W
components taken from the second row of the absolute matrix.
Tip: "Absolute", in this context, means an accumulation of all transformations from the child to the up-most parent. In a FireMonkey 3D form, the absolute position is just relative to the origin of the coordinate space. In case of a screen projection, the position is determined in pixels. In case of a camera projection, it depends on camera position and parameters.
